Square’s founder and CEO Jack Dorsey said in a release: Square is thrilled to welcome Vinod to our board. We have worked closely with Khosla Ventures since our inception and Vinod’s expertise, history and input will be a tremendous asset to our company as we continue to grow.

Having someone with Khosla’s entrepreneurial experience on a board is a big win for Square. Khosla co-founded Sun Microsystems. He went on to become a general partner at Kleiner Perkins and then founded his own venture fund Khosla Ventures in 2004. Clearly Khosla has experience advising the big guys in the tech world, and this input will be invaluable for a growing company like Square.
